  • Moving blade for thermic axial turbomachines
    Patent number: 4284388
    Abstract: The invention finds application in the manufacture of working blades of a length exceeding that of the blades known so far, without infringing the limitations issuing from flow considerations and strength of the rotor. The blade comprises two different sheets deliminated by a suitably selected intermediary cross section of the blade. Each of the sheets is formed according to a different law dictated by strength and flow considerations. Beginning from the cross-section which delimits the sheets, the sheets are twisted in opposite directions.
